character width

character width

[Steffen Wolfrum]

Hi,

for fine-adjusting I need to have a variable horizontal space  
sometimes the width of "999" sometimes of "1", for example.
Is there a command that reads the width of a character so it can be  
used in some kind of horizontal space?

There is a \fontcharwd primitive to measure the width of a single
character is a specific font:

   \hskip \the\fontcharwd \font `1

but it may be easier to put the number(s) in a box and measure the
width of that:

   \setbox\scratchbox=\hbox{999}%
   \hskip \the\wd \scratchbox

Yes, that's it. Thank you!

But can it also be defined in a more handy   \MySpace[999]   ?
Sorry, I tried some \def ... but didn't succeed.

Hi Steffen,

your solution based on the method provided by Taco.

\def\MySpace
  {\dosingleempty\doMySpace}

\def\doMySpace[#1]%
  {\setbox\scratchbox=\hbox{#1}%
   \unskip\hskip \the\wd \scratchbox}

\starttext

Text\MySpace[999]Text

Text\MySpace[999] Text

Text \MySpace[999]Text

Text \MySpace[999] Text

\stoptext

Or perhaps just:

\starttext
Text\hphantom{999}Text
\stoptext

?

Cheers, Peter

Hi Peter,

right this also works but we wont care about spaces in the souce.

Look:

\starttext

Text\hphantom{999}Text

Text\hphantom{999} Text

Text \hphantom{999} Text

\stoptext


Antoher solution for the spacemacro:

\def\MySpace
  {\dosingleempty\doMySpace}

\def\doMySpace[#1]%
  {\unskip\hphantom{#1}\ignorespaces}

\starttext

Text\hphantom{999}Text

Text\hphantom{999} Text

Text \hphantom{999} Text

\stoptext

and we have always the same gap.

" \hphantom " ! What a promising word for exactly what I needed!
Again and again I am surprised how many (strange) commands there  
exist. Where does \hphantom come frome? Where is it documented?

Thank you for your replies! But it could be even better:

As I need, finally, a construct like ...
\writetolist[Test]{}{{\hphantom{999}}{\hfill}\bf{Nicely centers TOC  
entry}{\hfill}\it 999}
... I would like to make sure that both manually entered numbers are  
the same (I don't want to risk a typo!).

So I'd like to use something like \def\FakePageNumber{999}, using  
\FakePageNumber at the beginning and the end of the above line.

The following worked ...
\expanded{\writetolist[Test]{}{\hfill {\bf Nicely centers TOC entry}  
\hfill \FakePageNumber}}
... but not in combination with \MySpace or \hphantom anymore:
\expanded{\writetolist[Test]{}{???\hfill {\bf Nicely centers TOC  
entry} \hfill \FakePageNumber}}

Could someone please help me over this "expanded/argument/ 
whateveristheproblem" gap?


Thank you very much,
Steffen

Hi Steffen,

I presnt you a few solution to your problem, I don't how it 
should look to you. 

<example>

\def\FakePageNumber{999}

\starttext

\placecontent

\section{Knuth}

\input knuth

% your solution

\expanded{\writetolist[section]{}{\hfill{\bf Nicely centers TOC entry}
\hfill\FakePageNumber}}

% solution 1

\writetolist[section]{}{\hfill {\bf Nicely centers TOC entry} \hfill \llap{\FakePageNumber}}

% solution 2

\writetolist[section]{}{\hfilll bla \hfilll \llap{\FakePageNumber}}

% solution 3

\writebetweenlist[section]{\hfilll bla \hfilll \llap{\FakePageNumber}}

\section{Knuth}

\input knuth

\stoptext

</example>
